Why will they be ashamed?
Radak: Their Nevu'os were not fulfilled. Malbim ? it will be known that their Nevu'os were mere imagination.
What is the grammatical form of "b'Hinav'oso"?
Radak: This is Makor (like a gerund) with an added Sov. We find like this in a Mishnah (Avos 5:1) ? it was possible Lehiba're'os (to be created) in one Ma'amar.
What is the significance of wearing "Aderes Se'ar"?
Rashi: This is the custom of enticers ? they wrap themselves in their Talesim as if they are Tzadikim, so their lies will be accepted.
Radak: False Nevi'im dressed in sackcloth and Aderes Se'ar, to portray themselves as Perushim (people who refrain from physical pleasures), Tzadikim and straight people who do not lie.
What do we learn from "Lema'an Kachesh"?
Rashi: This is why enticers dressed like Tzadikim, so their lies will be accepted.
Radak, Malbim: When their Nevu'os are not fulfilled, they will be ashamed. They will abandon their deeds, visions and dress, in order to deny that they ever prophesized.
